Summary: I've been looking for a mouse with fine grained placement capability. Had high hopes for this one. However, it didn't pan out. I found it slow and not any more accurate than a standard Logitech laser mouse.
Summary: I am surprised by all the glowing reviews for this mouse. Perhaps there is a defect in mine, but it eats batteries like nothing else. I keep two sets of rechargeable AAAs around because I was throwing away too many batteries at first to make the mouse worth while. I swap them out probably close to once a week (with constant usage at a 9-5 job). Otherwise, the mouse is pretty great. It drops connection occasionally, but not often enough for me to consider it a problem.
Summary: installing this mouse is simple and straightforward. However, after a very short period of use, it disconnects and requires uninstall/reinstall. The manufacturer's website has poor user support information.
Summary: I have a relatively new Macbook Pro (mid-2012) and I know my bluetooth is working well. I've never had problems with it otherwise. But with this mouse the bluetooth signal is dropped constantly! It's very annoying and interrupts workflow each time. Plus the buttons on the mouse are too high up on the mouse body. They should be just above the middle of the body of the mouse. The placement of the buttons from tip of mouse to back of mouse is well placed though.
Summary: Pros: - 5 buttons - Nice case Cons: - Tiny - Frequently lost connection I really wanted to like this mouse. Having a bluetooth mouse with some thumb buttons for gaming on the laptop would have been awesome, but this thing was just so freakin' small I just couldn't use it for any extended period of time (read: 10 minutes). The ergonomics are great, but needed to be scaled up about 1.5x.
Summary: This mouse is so small that all the features that it has become pretty much obsolete. Your hand will cramp up after using it for a while because of its small size. Don't know what the manufacturer was thinking when coming up with the design but seriously this mouse was not intended for an adult's hands. It also has difficulty connecting via Bluetooth sometimes, but everything else is fine. Scrolling, clicking, moving, everything works fine.
Summary: I'm very disappointed by this mouse. I'm using it for about one year with two different laptops. The first one I received worked only for one week and then it stopped after small 2-3 cm fall on the table. I got it replaced and the second one works, but is annoying. - It looses connections very often, so that you have to pair it with computer again.
